Can u do these for me plz fast

Answer:

B

Step-by-step explanation:

B

the vertex is (-5,-2) which eliminates A and C. D says that the x intercepts are both positive which is obviously incorrect making B the correct answer

Answer: 16%

Step-by-step explanation: Because if you look at that denominator then you can see that its 25 so if you multiplied that by 4 then you'll get 100 which is 100% so whatever you do to the denominator you have to do to the numerator so 4x4 is 16 so thats 16% and there you go.

Step-by-step explanation:

to calculate common ratio

=second term divided by first term

im pretty sure its 74

Answer:

[tex]\text{For topic A }:0.99\\\text{For Topic B}: 0.6875[/tex]

Step-by-step explanation:

Topic A: Two books are ordered

Topic B: Four books are ordered

Let X= number of books arrived

The probability that a book actually arrives in time is 0.9

i.e., p=0.9

For Topic A:

[tex]P(X\geq 1)=P(X=1)+P(X=2)\\\Rightarrow P(X\geq 1)= \;^2C_1 (0.9)^1(0.1)^(2-1)+\;^2C_2 (0.9)^2(0.1)^(2-2)\\\Rightarrow P(X\geq 1)=0.18+0.81\\\Rightarrow P(X\geq 1)=0.99[/tex]

For Topic B:

[tex]P(X\geq 2)=P(X=2)+P(X=3)+P(X=4)\\\Rightarrow P(X\geq 2)=1-[P(X=0)+P(X=1)]\\\Rightarrow P(X\geq 2)=1-[\;^4C_0(0.5)^0(0.5)^4 +\;^4C_0(0.5)^1(0.5)^3]\\\Rightarrow P(X\geq 2)=1-[0.0625+0.25]\\\Rightarrow P(X\geq 2)=0.6875[/tex]

Answer

24

Step-by-step explanation:

2:2 = 8

45 / 5 = 168

168 - 45 = 123

123 - 45 = 78

78 take away the 7 is 8 , 8 x 5 = 40 / 8 = 24

Answer:

$5(p)+$2(m) ≤ $45

Step-by-step explanation:

If you have a maximum of 45 dollars you are only able to spend 45 dollars or less so the variables that are filled in with the amount of pineapples and mango´s Carla wants to buy must be less than or equal to 45

Step-by-step explanation:

Answer:

L(13) = 200

Step-by-step explanation:

Linear function:

A linear function has the following format:

[tex]y = mx + b[/tex]

In which m is the slope(how much y changes when x changes by 1) and b is the y-intercept(value of y when x = 0).

Finding the slope:

L (5) = 100 and L (9) = 150.

The slope is given by the change in the output(L, which is equals to y in the general formula) divided by the change in the input(x).

Change in the output: 150 - 100 = 50

Change in the input: 9 - 5 = 4

Slope: [tex]m = \frac{50}{4} = 12.5[/tex]

So

[tex]y = 12.5x + b[/tex]

L (5) = 100

So [tex]y(5) = 100[/tex], which means that when [tex]x = 5, y = 100[/tex], and we use this to find b.

[tex]y = 12.5x + b[/tex]

[tex]100 = 12.5*5 + b[/tex]

[tex]b = 100 - 12.5*5[/tex]

[tex]b = 37.5[/tex]

So

[tex]L(x) = 12.5x + 37.5[/tex]

a. Determine the value of L (13)

L when [tex]x = 13[/tex]. So

[tex]L(13) = 12.5*13 + 37.5 = 200[/tex]

Answer:

its 8:9

Step-by-step explanation:

It would be 8 because you can see that the top row multiplies 16 by two in the exact spot where the missing number is.

Answer:

1/3

Step-by-step explanation:

let a = adults

so then 2a = children

a/2a(+a) = a/3a

Answer:

25

Step-by-step explanation:

In this it's going to be pretty simple.

[tex]b^{2}[/tex] is going to be -3 * -3 = 9

When you have a square you multiply the number by itself.

So

9 - 4 * 1 * -4

here you have to remember order of operations.

Please - Parens

Excuse - Exponents

My - Multiplication

Dear - Division

Aunt - Addition

Sally - Subtraction.

Multiplication and Division are done at the same time left to right

Addition and Subtraction are done at the same time left to right.

So

9 - 4 * 1 * -4

You do the multiplication first.

4*1 = 4

4 * -4 = -16

Now you have

9 - - 16

This turns into

9 + 16

your answer is 25.

Here's a trick when compareing fractions: turn them into percents then try it from there Hth!!

Answer:

the second one is the exponential function

Answer:

1)

(x + 3)(x + 4) = x^2 + 4x + 3x + 12 = x^2 + 7x + 12

Instead of multiplying 3 and 4 the student added them which gave them the answer of 7 when the correct answer is 12.

2)

a) x^2 + x - 2

b) x^2 - 7x + 10

c) 4x^2 - 1

d) x^2 + 10x + 25

Step-by-step explanation:

a. (x - 1)(x + 2)

x(x) - 1(x) + 2(x) - 1(2)

x^2 - 1x + 2x - 2

x^2 + x - 2

------------------------------------------

b. (x - 5)(x - 2)

x(x) - 5(x) - 2(x) - 5(-2)

x^2 - 5x - 2x + 10

x^2 - 7x + 10

------------------------------------------

c. (2x + 1)(2x - 1)

2x(2x) + 1(2x) - 1(2x) + 1(-1)

4x^2 + 2x - 2x - 1

4x^2 - 1

------------------------------------------

d. (x + 5)^2

(x + 5)(x + 5)

x(x) + 5(x) + 5(x) + 5(5)

x^2 + 5x + 5x + 25

x^2 + 10x + 25

Answer: they contain valuable items and are very interesting

Step-by-step explanation:

Answer:

180x²(3x⁴+2)⁴+240x³(3x⁴+2)³

Step-by-step explanation:

we need to break this up using the chain rule

(3x⁴+2)=u

so we have

So now we take 3x⁴+2 and take the derivative (which I will assume you know how to do, if not lmk)

which is 12x³

we now need to take the derivative of u⁵=5u⁴

Mulitply these together

60x³u⁴=60x³(3x⁴+2)⁴

do the same thing again

60x³u⁴

we now need to do the mulitplication rleu

(60x³)'(u⁴)+(60x³)(u⁴)'

=

180x²u⁴+60x³*4u³

simplify

180x²(3x⁴+2)⁴+240x³(3x⁴+2)³

while you could do more to simplify it, it would get really messy

Step-by-step explanation:

Answer:

4sides

Step-by-step explanation:

these is answer 4 sided

When the equation of any line reads "y = a number",

its graph will always be a horizontal line, meaning zero slope.

So the equation y = -10 has a slope of 0 which

means its a flat or horizontal line.

Please let me know if you have any questions

Answer:

2) 98/15 meters

21/5 + 7/3 = 63/15 + 35/15 = 98/15

3) 7/12 of the loaf

1/3 + 1/4 = 4/12 + 3/12 = 7/12

4) 19/8 inches

9/8 + 5/4 = 9/8 + 10/8 = 19/8

5) 73/6 cups

29/3 + 5/2 = 58/6 + 15/6 = 73/6
